Heh, you bet it's mostly adventure! Even my Uncle Donald, who's like, the most normal guy and the biggest scaredy-cat in the world, used to go adventuring with Uncle Scrooge all the time until my bros and I were born! I don't think any of my family's truly normal. Scrooge's parents? Still alive because Castle McDuck was built on top of magic druid stones that grant them immortality. Uncle Gladstone? Literally has magical luck in him. Uncle Fethry? Has a giant mutated krill for a friend!
